i spent over an hour recently trying to figure out how to false set an M800 with no luck. ive tried it by the prog book several times but cant seem to make sense of it.

so could somebody give me a simplified short rundown on the sequence. please.

Never tried it on the M series but on the 2500 in engineer 3, you select the ward to test (1 for A etc), press enter, select the zones you want to include (eg 1001, 2034) press enter, then you can turn all the outputs off or on, press enter to start, do your test and "0" unsets. Useful in high schools where it would take forever to omit everything. Also, IIRC the zones have to be ascribed the "Activity" attribute for it to work.

If you have spare wards, you could make a couple of zones part of a new ward for testing purposes, and test that way.
